Calling treatment method for use under next generation network architecture

Abstract

This invention relates to a method for realizing NGN structure and a call process method under the NGN structure, in which, the number match is not limited by DigtMap. In this invention, the called number is divided into a character head and a successive number in the incoming call, in which, the character head is matched via the DigtMap and reported to the soft switch by the gateway for route analysis, then the successive number is reported to the soft switch interactively in other ways, which sends it to the successive node of the link for number match till the local office informs that the numbers are complete and the segmented call numbers are sent to the gateway interactively in the outgoing call.

Description

technical field [0001] The present invention relates to a realization method of a next generation network (Next Generation Network, "NGN") framework, and in particular to a realization method of an R2 signaling mode under the NGN framework. Background technique [0002] The traditional telephone network is usually called the Public Switched Telephone Network ("PSTN" for short), which has developed for more than 100 years from the most primitive manual switching network relying on operators to today's digital program-controlled telephone network. The basic principle of the traditional telephone network is to use some connection technology to establish a circuit between two telephones that can transmit voice. With the development of digital communication technology, the internal structure of today's telephone network has been digitized. The modern digital telephone switching network is based on Time Division Multiplexing (TDM) technology, and establishes an exclusive circuit ...

Problems solved by technology

[0017] On the surface, this method improves the efficiency of number matching, but in fact it not only makes the system design complicated, but also because the solution reports the called number based on the matching result of DigitMap, it still cannot solve the problem that a DigitMap parameter cannot be wildcarded. Called number problem

Therefore, the softswitch must carry multiple DigitMap parameters when sending address events, and the gateway needs to perform multiple segment matching according to the DigitMap parameters in different orders, which makes the implementation more complicated and reduces the overall efficiency of the system.

[0018] In practical application, the above scheme has the following problems: the R2 signaling interaction method between the softswitch and the gateway under the NGN network architecture proposed by IETF and ITU-T cannot solve the problem of matching all possible called numbers, and cannot guarantee the dialing The quality of service is called the quality of service; among them, the collection method suggested by IETF realizes the full matching of numbers through timer overtime, resulting in a long connection time, while the segmented matching method suggested by ITU-T is realized by matching each segment of numbers separately, and multi-segment The logical processing relationship between DigitMaps makes system implementation very difficult and increases system complexity

[0019] The main reason for this situation is that the R2 signaling interaction method between the softswitch and the gateway under the existing NGN network architecture uses DigitMap to match the entire number, resulting in the need to implement DigitMap for all possible number rules; The method is to confirm whether the number is complete through the timeout mechanism, resulting in a long connection time, and the logical processing of the segmented method is complicated, which increases the complexity of the system
